Green land that functions as rainwater catchment is covered with an impermeable surface, so runoff will increase and infiltration capacity will decrease. The method that can be done to reduce runoff is by using an impermeable cover with green plants. The pavement model used is an environmentally friendly pavement that can function to reduce surface runoff. The surface runoff coefficient is an indicator of land conditions. Surface land with the pavement will produce a large runoff coefficient while on natural land the runoff coefficient will be small. The grass block paving experimental model allows it to be used more widely because it has pores that can reduce runoff and increase the volume of water that enters the soil. The test results show differences in the runoff coefficient resulting in the tested land cover variations. The average runoff coefficient on land with a sandy loam texture without pavement is 0.41. Meanwhile, the average runoff coefficient for grass block paving is 0.43. On land with impermeable pavement, the runoff coefficient ranges from 0.50 to 0.70.

Salah satu satelit penyedia data hujan yang cakupan wilayahnya termasuk Indonesia adalah TRMM JAXA. Penelitian ini menguji seberapa jauh kedekatan data hujan dari TRMM JAXA dibandingkan data hujan pengukuran. Tahapan dimulai dengan mengumpulkan data hujan dilanjutkan dengan perhitungan hujan rancangan, dan mengukur penyimpangannya dengan nilai RMSE dan BIAS. Hasil yang diperoleh menunjukkan bahwa data hujan dari satelit TRMM JAXA di Wilayah Sumbawa cenderung underestimate dan memiliki tingkat akurasi yang cukup dibandingkan data hujan pengamatan dengan penyimpangan rerata sebesar -0.05. Besaran hujan rancangan yang dihasilkan dari analisis frekuensi menggunakan data hujan satelit TRMM JAXA memiliki penyimpangan yang cukup besar yaitu sebesar 21%.

Semakin tinggi koefisien keseragaman tetesan menunjukkan kinerja jaringan yang semakin baik. Dan kinerja terbaik dari jaringan irigasi tetes dapat diperoleh dengan mengoptimasi parameter-parameter yang mempengaruhi, seperti panjang dan kemiringan pipa lateral, diameter dan jarak antar emitter, serta panjang durasi penetesan. Penelitian ini dijalankan dengan metode eksperimental di Laboratorium dengan cara mengamati dan mengukur langsung hasil tetesan di masing-masing emitter menggunakan pipa lateral dari PVC. Kemudian perhitungan koefisien keseragaman dihubungkan terhadap parameter aliran pipa dripline untuk mendapatkan parameter yang menghasilkan keseragaman terbaik. Penelitian menghasilkan bahwa keseragaman tetesan optimum diperoleh pada kemiringan pipa lateral terbaiknya yaitu 0.2% dan panjang pipa lateral kurang dari 12 meter. Sementara semakin besar diameter lubang penetes menghasilkan keseragaman tetesan yang semakin menurun, dan semakin besar jarak antar penetes menghasilkan keseragaman tetesan yang semakin baik.

Nowdays, this catchment area in the UDS has a fairly large and rapid change in land use, from agricultural land to housing, building shops, offices and other buildings, so causing floods in several area. New construction and maintenance of drainage channels have been carried out by several agencies, both the City, Provincial, and Central Government, but the development are still partial or not comprehensive, so that many inundation problems become moved to other place and not resolved properly. For this reason, it is necessary to do zonation of the drainage network and its catchment area in order to facilitate the arrangement of drainage network. The objectives of this study are to find out the drainage network and catchment area of each drainage channel, so that the mapping can be made, and to evaluate the drainage channels capacity or the ability of the drainage channels to accommodate runoff. The conclusions of research are the results of mapping or zonation of the UDS are divided into 20 Primary Drainage Blocks in the Right UDS and 10 Primary Drainage Blocks in the Left UDS, the capacity evaluation of the existing drainage channel in this system is that most primary channels are still able to accommodate flood discharge, except the Sekarbela, Asrama Gebang, and Abian Tubuh Mayura primary channel. With zonation and evaluation the capacity of this drainage channel, planning for the development and maintenance of drainage system can be integrated and comprehensive, so that flood control can be better in accordance with its priorities.
