Abstract Most of the population in Indonesia uses groundwater to meet need for clean water. With rapid growth, there has been an increase conversion open space land into residential, offices, and commercial areas. The increases impervious surface throughout city could impact availability water future. Implementation conservation is needed ensure long term Rainwater harvesting systems are one me...

One sustainable method of stormwater management is surface infiltration with retention. Proper design facilities ensures a reduction in flood risk within urban catchments. However, this not possible without considering the key parameters such facilities. The aim paper to determine influence characterizing catchment area on size research used SWMM 5.1 and Statistica software. It was carried out ...

In this paper, permeable pavement, which is a sustainable infrastructure, designed with subsurface micro detention pond storage, called, StormPav. The product cylindrical hollow space of 70% void volume and occupied about 0.19 m3/m2 pavement area for rainwater harvesting device. experimental investigations application asa were conducted in the laboratory. hydrology parameter variables examined ...

Affected by regular tides, bidirectional water flows play a crucial role in surface river systems. Using optimization theory to design a water quality monitoring network can reduce the redundant monitoring nodes as well as save the costs for building and running a monitoring network. A novel algorithm is proposed to design an optimum water quality monitoring network for tidal rivers with bidire...

Among the various factors that contribute to flood risk, heavy storms, inadequate storm drainage systems, and the concentration of population and assets have usually been considered to be fundamental factors affecting flood damage. Climate change is also a real threat, bringing heavier and more frequent storms. This study presents a methodology for comparatively evaluating the impact of the flo...

The usefulness of a hydrologic model is directly related to its application and how well it is calibrated. Calibration is a subjective exercise where model parameters are adjusted to reduce discrepancies between measured data and modeled predictions. Automated calibration can be used to accelerate the model calibration process, minimize modeler bias, and increase the goodness of fit between mea...

In recent years, GIS applications in water resources management have become widespread and diverse in the Province of Ontario, Canada. Application areas include urban infrastructure master planning for storm and sanitary drainage systems, water distribution, watershed planning, and regional groundwater protection. This development has occurred despite the challenge faced by users that base data...
