Abstract

The high population growth have led to higher demand for housing and supporting infrastructure, but the area is relatively fixed. This leads causing high conversion of open space to be built. So if it rains, there is always a pool. In downstrean Sub Water Catchment Area of Watu is one of the quite interested location for developers to build housing. Recorded at the studied location, increased number of sites pool with long pool and varying height of pools. On the other hand there has been no approach to handling spatial puddle of water, so as to create spatial land by providing an appropriate space for water to enter the maximum into the ground through infiltration process. The purpose of this study is to provide the spatial direction of drainage techniques to reduce puddles on the Lower Sub-basin Watu. The method used were descriptive method, through the analysis of land use, water absorption analysis, analysis of the rate of surface runoff and drainage system analysis. Analyses were performed on data with the data existing in the year 2010 based on the end year plan from Kota Malang Spatial Plan Year 2010-2030. Based on the analysis, in 2010, woke up the living space is 207.36 ha (31.82%) and 444.36 ha of open space (68.18%). In the year 2030 an increase in space woke up onto 417.97 ha (64.13%) followed by reduction of open space to be 233.75 ha (35.87%). A decrease in water absorption of the Year 2010 m3/year 240,888.40 to 117,444.40 m3/year in the year 2030. And an increase in flow rate on the surface of m3/second 118.622 136.874 m3/second Year 2010 to the Year 2030. From the analysis of the drainage system obtained 33% of the existing conditions are not available drainage, drainage channels covered 17% of the building, 6% of the drainage channels double as irrigation canals, drainage channels 10% too small, 14% with no inlet or drainage channels lip channels higher than face the street, 11% poorly maintained drainage channel or channels overgrown with grass, and 8% tract in good condition.By looking at the result of data analysis and assessment of existing theory, then the directives of spatial technology to reduce the pool of drainage in Sub Water Catchment Area of Watu is the eco-drainage technology or drainage eco-friendly environment, which synergize with the spatial practices of water conservation. Spatial direction of eco-drainage in the Lower Sub-basin Watu are (1). The separation between the drainage channel that drains domestic wastewater with rain water drainage, (2). Preparation of individual wells on the main road corridors, particularly in the residential building medium, large residential, commercial and service facilities, industry and warehousing facilities, education and health facilities, (3). Making collective wells at high density buildings, especially residential buildings are very small and small / simple, and (4). Creating a catchment pond for formal housing in the topography of the basin.

Abstract

Research attempts to understand the potential and demand of water and the water balance, the review on water balance at Watershed Renggung to ensure the satisfaction of the demand of irrigation and domestic waters at Central Lombok District. In this research water potential is 243.34 millions m3 comprising to 22.59 millions m3 river water, 252.51 millions m3 HLD supplement, and 1,309 mm rainfall or equaled to 252.51 millions m3. River water supply is calculated based on 80 % (Q80) dependable discharge from AWLR Renggung- Ponggong in the period from 1992 to 2011. Discharge is used as the guidance to determine water availability at Watershed Renggung. Result of analysis indicates that the maximum discharge is available at 3.658 m3/ second on March. The average debit is 0.721 m3/second, while the minimum discharge is 0.608 m3/second on October. The current water demand for multi-sectors is 225.11 millions m3. These multi-sectors include domestic, irrigation, animal husbandry, fishery and industry. For the industry, the water is supplied only to the industry in the sub-district at the Watershed. The analysis devices for water availability involve the analysis of rainfall and the analysis of surface water.The water demand total at Watershed Renggung for the next 25 years is estimated in the average as 227.58 millions m3. This total figure consists of: 208.40 millions m3 for irrigation water, 7.59 millions m3 for domestic water, 5.40 millions m3 for animal husbandry, 4.90 millions m3 for fishery, and 1.30 millions m3 for industry. The prediction of water demand total from 2011 to 2031 based on Water Demand Index (IKA) Standard of NSAD at NTB Province is 94.75 % in average, meaning that the water use rate is critical. By 2036, IKA is assumed as 101.87 meaning that the water use rate will be deficit.Keywords: water demand, water availability, water balance

Abstract

Abstract: This study explores accuracy of short term rainfall disaggregation model by modeling rainfall runoff. Storm hydrographs show rapid responses to rainfall with a short time to peak. The spatial rainfall disaggregation process used multivariate daily rainfall (MuDRain) model on 4 manual rainfall rain gauges (MRR) and 3 automatic rainfall rain gauges (ARR) used as reference the hydrographs were satisfactorily modeled using the Hydrologic Engineering Centre–Hydrologic Modeling System (HEC-HMS). Parameter calibrations were done on case 1 that rainfall runoff modeling used the rainfall data from 7 rain gauges (MRR and ARR). Model validation (case 2) used the rainfall data from 3 rain gauges (ARR). The efficiency indexes of (case 1) and (case 2) are 0.97 and 0.74, respectively. Based on these preliminary findings, it could be suggested that rainfall disaggregation would be able to serve reasonably well in regulating basic hydrological functions.Key words: rainfall, runoff, disaggregation, MuDRain
