Lesti watershed is a sub basin of Brantas River located in Malang Regency, which is the main source of inflow and sediment loads for the Sengguruh Dam. Human activities change the type of land cover by deforestation for the expansion of agricultural and residential areas. It makes a rapid increasing of runoff and discharges that were potentially carrying sediment into Lesti River. To measure surface runoff in a watershed can be held by modeling rather than directly in the field, it is cheaper and more effective with accurate results. This study is based on Soil Conservation Service (SCS) formula to illustrate surface runoff level by knowing curve number distribution. Using models based on land use changes in 2010, 2012 and 2017, generated by AV SWAT software, shows that increasing CN value each year affects the surface runoff, so there is a relationship between land use and runoff. The average CN value in 2010 is 63.644, 2012 is 63.942, 2017 is 65.49, while the average surface runoff in 2010 is 800.28, 2012 is 823.26, 2017 is 828.009. Conservation treatment on the area with a high CN value can reduce the surface runoff. It shows that watershed performance is getting better.

Data collection based on satellite TRMM (Tropical Rainfall Measuring Mission) presents one of the good alternatives in estimating rainfall. TRMM technology can minimize manual rainfall recording errors and improve rainfall accuracy for hydrological analysis. The analysis method used in this research is divided into 3 (three) stages, namely Hydrology analysis, Statistical Analysis and Artificial Neural Network Analysis. From the results of TRMM JAXA analysis in the Temef Watershed Area of East Nusa Tenggara Province obtained TRMM JAXA satellite rainfall relationship to observation data shows rainfall patterns between the two data are interconnected but for cases with very high observation rainfall, TRMM rainfall data tends to be low. From statistical method analysis, the relationship between observation rainfall and TRMM JAXA rainfall obtained results with a "Very Strong" interpretation indicated by the results of 9 years calibration and 1 year validation where the selected equation is a polynomial equation (y=-0,0123x2 + 1,5553x + 20,222). Rain data correction results simulated with Debit data to see the relationship between rain and discharge that occurred, this analysis using Artificial Neural Network with Backpropagation method, the results showed a "Strong" interpretation where statistically the value of Nash-Sutcliffe Efficiency (NSE) 0.920, the coefficient value of correlation of field discharge and TRMM rainfall is 0,877 % and the relative error occurred is 2,62%.

The Lempake Dam currently functions as a dam that provides raw water for irrigation and clean water, besides its indirect functioning as the only flood control dam in the Karangmumus sub-watershed. Current conditions indicate that the Lempake Reservoir has experienced decreased capacity from year to year. At the normal water level, the reservoir capacity of Lempake Reservoir in 2013 was 0.76 million m3 and in 2018 was 0.39 million m3. Therefore, efforts are needed to control reservoir sedimentation and reservoir operations to allow the Lempake Dam to continue to function as a flood control reservoir. This study was carried out by analyzing the volume of sedimentation in the reservoir using the ArcGIS program and analyzing the flood hydrograph at the site by flood routing at the Pasar Segiri River, optimizing reservoir operations, and mapping flood inundation using the RAS Mapping program (HEC-RAS). The results showed that the storage volume in 2020 is predicted to be 0.241 million m3 with an annual sediment rate of 0.074 million m3. From the flood routing analysis and optimization of reservoir operations, the cross-sectional capacity of the river in Pasar Segiri (safe limit elevation +3.30 m) is insufficient for a flood discharge of a return period of more than 2 years (more than 222.14 m3/sec) for Scenario 1, and of more than 5 years (more than 320.48 m3/sec) for Scenario 2.

Wuno Reservoir is located in Sigi Biromaru District, Sigi Regency, Central Sulawesi Province. It is planned for 50 years. This analysis to known the condition of ideal land use so that the life time of the reservoir reaches 50 years. Trend of land use change, erosion and sediment rate estimation using the ArcSWAT model. During 2008-2016, natural forest land use showed a downward trend, while mixed gardens, shrubs, fields and settlements showed an increasing trend. The erosion rate in 2008-2010 increased by 72.5%, in 2010-2012 it increased by 1.45%, in 2012-2014 decreased by 0.09% and in 2014-2016 increased by 0.98%. In 20082016 Low BEHI area was reduced by 3.74%, medium BEHI was increasing by 14.11%, BEHI High increased by 16.57% and BEHI Very High increased by 12.64%. This shows that the rate of erosion and the extent of BEHI are influenced by changes in land use. Based on the results of analyzing the lifetime of the reservoir, changes in land use also affect the reduced useful life of the reservoir. Vegetative land conservation efforts are adjusting forest areas so that rate of erosion decreases by 62.75%. Mechanical land conservation efforts in the form of the construction of 6 check dams so that weight of sediment decreases by 89.24%.

There are two basic methods to calibrate the hydrological model: (1) the trial and error procedure; (2) the automatic calibration. The problem in the calibration method is the determination of the initial value of the parameters. This poses a problem for beginner model users. This paper presents the calibration results of surface runoff parameters in the hydrological tank model using recursive digital filter method and the master recession curve. The results indicate that the Recursive Digital Filter as a surface runoff separation method can be used for the initial approach to calibrate the tank model parameters

Kekeringan dan kurangnya air bersih jadi permasalahan tahunan yang di hadapi Kabupaten Probolinggo. Terdapat sebanyak 16 desa di 7 kecamatan yang termasuk daerah rawan kekeringan. Metode analisa kekeringan yang digunakan adalah Standardized Precipitation Index (SPI) dan Decile Index (DI). Hasil indeks kekeringan dibandingkan dengan ENSO (El Niño–Southern Oscillation) untuk mengetahui kesesuaian dengan keadaan di lokasi studi. Indeks kekeringan yang memiliki kesesuaian paling besar dengan ENSO tersebut kemudian dibuat peta sebarannya menggunakan software ArcGIS 10.3. Analisa kesesuaian dilakukan dengan pembacaan pola kekeringan melalui grafik surplus dan defisit terhadap nilai SOI serta analisa korelasi dengan SOI dan data curah hujan bulanan. Dari ketiganya menunjukkan bahwa DI memberikan nilai yang lebih besar terhadap kejadian ENSO dibandingkan metode SPI. Hasil studi berdasarkan metode SPI menunjukkan bahwa tahun terkering di DAS Pekalen terjadi di tahun 2007, 2004, 2009, dan 2001, sedangkan dengan metode DI tahun yang paling kering terjadi di tahun 2006, 2007, dan 2009.Drought and lack of clean water are annual problems that Probolinggo Regency faces. Thereare 16 villages in 7 (seven) sub-districts that are classified as drought-prone areas. The drought analysismethod used is the Standardized Precipitation Index (SPI) and the Decile Index (DI). The results of the droughtindex were compared with ENSO (El Niño – Southern Oscillation) to determine suitability with conditions inthe study location. The drought index which has the greatest compatibility with SOI data pattern will be drawn on the drought distribution map using IDW interpolation with the ArcGIS 10.3 programs. The suitability analysis is carried out by reading the drought pattern through graphs of surplus and deficit to the SOI value and correlation analysis with SOI and monthly rainfall data. Of the three, it shows that DI provides a greater value for the incidence of ENSO than the SPI method. The results of the study based on the SPI method show that the driest years in the Pekalen watershed occurred in 2007, 2004, 2009, and 2001,while with the DI method the driest years occurred in 2006, 2007, and 2009.
