Decision Support System (DSS) for MSMA Integrated Stormwater Management Ecohydrology for Sustainable Green Infrastructure

Abstract

Abstract. Rapid urbanization has known to have several adverse impacts towards hydrological cycle due to increasing impervious surface and degradation of water quality in stormwater runoff. In the past, urban waterways have been confined to narrow river corridors with the channels canalised and concrete and other synthetic materials forming the bed and banks of the river. Apart from that, stormwater pollutants such as litter, debris and sediments in drainage system are common problems that can lead to flooding and the degradation of water quality. To solve this problem, implementing stormwater Best Management Practices (BMPs) proves very promising due to its near natural characteristics and multiple effects on the drainage of stormwater runoff in urban areas. This judgment of using BMPs depends on not only relevant theoretical considerations, but also a large amount of practical experience and the availability of relevant data, as well. To fulfil this task, the so-called Decision Support System (DSS) in MSMA Design Aid and Database system are able to assist engineers and developers in management and improvement of water quantity and quality entering urban rivers from urban regions. This system is also helpful when an expert level judgment procure some repetitive and large amount of cases, like in the planning of stormwater BMPs systems for an entire city catchment. One of the advantages of an expert system is that it provides automation of expertlevel judgement using availability of checking tools system.

“…(4) Hydrology Studies in Hydrology cross scales. At watershed, city, or other macro scales, such literature studies the changes of runoff mechanisms (e.g., processes of formation, evaporation, and infiltration) from the perspectives of Ecological Hydrology [22] , Natural Hydrology [23] , Watershed Hydrology, River Hydrology, Urban Hydrology, and Surface Hydrology, helping identify catchments in urban areas [24] with a particular focus on the balance of urban hydrological processes. At micro scales, studies of various stormwater management and control measures often focus on hydrological performance [25] , functions, and benefits, helping establish natural water cycles through constructed approaches.…”

“…Pollutant from the various sources of the catchment will leak and gather with sediment in river beds [22]. Therefore, river water quality degradation problems become even worse.…”
