This study aims to analyze the potential of water availability in the free intake of Wae Musur 1 and 2 which are used to meet the needs of functional and potential irrigation water in the Borong watershed, East Manggarai Regency. The method used in this research is quantitative analysis method. The calculated availability of water is surface water in the form of a reliable river discharge. Water requirements for functional and potential land are calculated based on the assumption that 1 hectare is equal to 1 liter / second. The analysis shows that the average availability of mainstay debit in January to December is 4,5 million m3/month. Balance sheet analysis shows that the mainstay discharge available for free intake of Wae Musur 1 and 2 is able to meet the needs of functional land irrigation water and is still surplus. Therefore, this surplus is used to meet potential land irrigation water needs. After analyzing the water balance, the potential for irrigation water needs is apparently still experiencing a surplus as well. Surplus ranges from 0,3 million to 6,3 million m3/month.

Changing open land to closed land will increase air temperatures in urban areas. Like the development of Malang Town Square which was built in 2005 which is not in accordance with the Regional Spatial Planning (RTRW) of Malang. The purpose of the study was to analyze the rainfall patterns from the impact of Malang Town Square development. The method used is to find monthly maximum daily rainfall data which is then analyzed and graphed to determine monsoonal rainfall patterns. From the two graphs it can be concluded that the graphs in the years before the construction of the highest rainfall pattern matos were in January but in the years after the construction of the highest rainfall pattern matos were in December. So that changes in land use have an impact on rainfall patterns in an area. This study only analyzes the impact of the construction of matos on rain patterns three years before development and three years after the construction of Malang Town Square

In the City of Tarakan, there is a network of drainage systems that have different dimensions and water debit sizes. In the Selumit River Basin drainage system, runoff often runs on the road when it rains. This is caused by existing runoff. Yet according to planning calculations and based on dimensional calculation results, the channel can still accommodate existing runoff discharge. This is caused by some inefficient channels. Inefficient channels can cause runoff. Based on efficiency calculations, the Selumit River Basin drainage system in Tarakan City is an efficient channel, with an average percentage of efficiency of 97%. This means that only 3% of the percentage of water that escapes from the difference in water entering the channel with water coming out of the drainage channel. According to the Efficiency calculation, there are several very efficient drainage channels, namely channels with scheme numbers 3, 4, 6, 7, 10, 13 and 14 with each value of efficiency percentage is 100%. And there are some inefficient channels among which are channels with the number scheme 1, 2, 5, 8, 9, 11, 12, 15, 16, 17, 18, 19, and 20, with each percentage value of efficiency is 93% , 84%, 99%, 99%, 98%, 99%, 99%, 95%, 98%, 97%, 97%, 99%, and 92%. The channel with the lowest percentage of efficiency is 84% found in the channel with scheme number 2. It means that the runoff water in the drainage channel is as complicated as between 2% -16%. Based on the analysis, an alternative solution to the problem of an inefficient drainage system was formulated is to streamline an inefficient drainage channel.

Clean water management in South Morotai District is managed by the Morotai Island District PDAM. The volume of the reservoir in the service area of South Morotai District is 450 m3 with a capacity of 25 liters/second sourced from the mangere spring. This study aims to determine the current reservoir capacity whether it is still able to meet the increasing demand for clean water throughout the year based on the projected population from 2017-2027. The population of the South Morotai District Service area in 2017 is 9.336 people. The projection of the population until 2027 is 19.371 people. Reviewed from the large production capacity of PDAM, the service area of South Morotai District has been able to meet the total customer needs of 8.018 liters / second in 2017 and 16.697 liters / second in 2027. Reservoir has not been able to serve customers' needs 24 hours a day, because water cannot be flowed continuously. This is because the reservoir volume is much smaller than the total needs of 735 m3 customers in 2017 and 1.443 m3 in 2027. For this reason, there must be a development of an increase in reservoir volume of 1.600 m3 in order to fulfill all customer requirements that are adjusted to the management criteria for clean water from Ditjen Cipta Karya PU 1996.

Penggunaan lahan merupakan salah satu faktor pengaruh atas terjadinya banjir. Banjir terjadi adalah dikarenakan limpasan dan resapan air yang tidak seimbang. Limpasan dipengaruhi oleh jumlah hujan, durasi hujan, daerah tangkapan hujan, dan kondisi penggunaan lahan atau juga penutup lahan. Penggunaan lahan di Kota Malang diartikan sebagai sebelum dan sesudah pengembangan penggunaan lahan di kawasan Jl. Veteran Kota Malang Â yang termasuk dalam daerah tangkapan hujan. Curah hujan pengamatan dihitung dari hujan harian maksimum bulanan rataâ€“rata 10 tahun sebelumÂ dan setelah pengembangan penggunaan lahan . Hasil pengamatan, pola hujan di Kota Malang tidak berubah, pola hujan Monsunal. sebelum dan sesudah pengembangan penggunaan lahan. Jumlah hari hujan sebelum pengembangan lebih lama tinggi dibandingkan saat setelah pengembangan penggunaan lahan. Dengan jumlah hujan yang lebih banyak namun hujan maksimumnya rendah terjadi pada sebellum pengembangan penggunaan lahan, sedangkan untuk curah hujan maksimum tinggi namun mempunyai jumlah hari hujan yang sedikit adalah sesudah pengembangan pengguaan lahan.
