Water becomes, every day, more scarce. Reliable information about volume and quality in each watershed is important to management and proper planning of their use. Data-intensive science is being increasingly needed in this context. Associated analysis processes require handling the drainage network that represents a watershed. This paper presents an ongoing work that explores geographic waters...

The application of the polder system for flood control in DKI Jakarta has become a must coastal areas, especially with construction sea dikes along coast as solution to anticipate tidal flooding. One thing consider when using is how much pump capacity and reservoir are needed. To answer this quetions, hydrological analysis been carried out several method approaches, starting from determining ra...

Abstract. Knowledge of the variability hydrograph outflow from urban catchments is highly important for measurements and evaluation operation sewer networks. Currently, hydrodynamic models are most frequently used modeling. Since a large number their parameters have to be identified, there may problems at calibration stage. Hence, sensitivity analysis limit parameters. However, current analytic...

This paper presents a comparative analysis of two hydrological models in the Storm Water Management Model (SWMM) software, namely, non-linear reservoir (N-LR) and unit hydrograph (UH), on urban catchment Cascina Scala, Pavia Italy. The were applied for simulation rainfall-runoff transformation 42 sub-catchments while flow routing underground channels was simulated by means De Saint-Venant equat...
