Drainage Channels

Tarakan City experiences problems with standing water during the rainy season, especially in the west Tarakan sub-district which is the center of Tarakan. This puddle not only submerged settlements and offices but also shops and access roads that caused considerable economic losses. An evaluation was carried out by using the Storm Water Management Model (SWMM). SWMM is a rainfall-runoff simulation model used for simulating the quantity and quality of surface runoff from urban areas. Based on the evaluation using SWMM software, the drainage system in Tarakan, especially in Jalan Mulwarman has several inundated channels, namely channels 2, 3, 4, 5, 6, 7, 11, 12, 13, 14. This is influenced by the dimensions of the drainage channel that cannot accommodate existing water runoff and sediment thickness that covers the drainage channels so that the capacity is reduced, if it rains it will cause puddles at several points in Tarakan City. In order to deal with these puddles, it is necessary to change the dimensions of the channel and routinely dredge sediments that cover the drainage channels.

Groundwater table depletion and increasing flood events can be easily realized in urban areas. It is necessary to improve existing storm water management systems for good quality water environment and reduced hydro-meteorological disasters while preserving our natural/pristine environment in a sustainable manner. This can be achieved through optimal collection, infiltration and storage of storm water. The need of sustainable storm water management is desired and optimal capture measure is explored in this paper. This paper provides a review of storm water management in urbanization and climate change context with a case study of Tokyo Metropolitan, Japan which could be helpful in mitigating the dual problems of groundwater depletion and flood events. This paper presents the overview of storm water run-off management in order to guide future storm water management policies. Also, the effects of different onsite facilities from water harvesting, reuse, ponds and infiltration are explored to establish adaptation strategies that restore water cycle and reduce climate change induced flood and water scarcity.

AbstractBioretention basins/rain garden is a very suitable low-impact development (LID) practice for storm water management around the globe. By using this practice in urban areas, flash flooding problems can be decreased and the environment of an area can be improved. The concept of bioretention was introduced a few decades ago and has been proven to be the best management practice (BMP) for storm water in urban areas. Due to urbanisation, natural surface areas are converted into hard surfaces such as roads, through which water cannot infiltrate into the ground. Due to this, infiltration decreases and surface run-off increases, which causes depletion of ground water continuously. In this study, we mainly explain the bioretention concept and its function as derived from different studies. This review includes different scientists’ results for the performance of the bioretention system at different locations. A summary of the research findings by different scientists on the performance of bioretention systems is also provided, including the hydrologic and water quality performances. Finally, future work necessary to enhance the performance and widespread use of bioretention systems is also explained.

Institutional Challenges

Increased flooding caused by climate change impacts is a challenge for many cities both in developing and developed countries. The existing storm water drainage systems in place have to be physically constructed and expanded to meet the water run-off challenge. This is an expensive run-off management undertaking for resource poor countries such as Tanzania. Landscape based storm water management (LSM) is put forward as a sustainable option to manage storm water run-off and it also addresses water scarcity problems in under-served urban settlement. However its implementation in cities that are faced with informal residential development is challenging because among other things, LSM requires land for implementation as well as the collaboration of different institutions, disciplines and actors. Drawing from data and information obtained from the Water Resilient Green Cities Africa (WGA) Project in two cities of Africa, this paper explores the planning and institutional challenges for LSM in Dar es Salaam, a rapidly urbanising city. The paper also presents opportunities inherent in the process some of which suggest that local institutions offer a critical platform to collaboratively plan and implement LSM in rapidly urbanising cities.

The Impact

Abstract As communities grows, the area covered by rooftops and concreted surfaces increases. Rain water which would have infiltrated, flows across these impermeable surface carrying pollutants along the way. This causes frequent flash floods in urban areas. Effective storm water management is needed for the sustainable development of communities. In this study the runoff generation for a small catchment is quantified and the effectiveness of low impact development (LID) practices (permeable pavements (pp) & vegetative swales) in mitigating the runoff at the source itself is studied using Storm Water Management Model (SWMM). The most influential design storm and the soil type pertaining to the study area were the determining factors for evaluating the impact of LID’s. The steady flow model and Hortons’s infiltration parameters for the soil type in study area were adopted for the analysis. The permeable pavements and swales performed well in reducing the runoff but the swales were less efficient in reducing the runoff, and the runoff reduction potential of permeable pavements and swales are 4.48% and 2.05% respectively. Runoff reduction is more efficient in case of combination of permeable pavements and vegetative swales as LIDs. The percentage reduction in runoff is about 6.05% and the efficiency of the combination type LID is about 17%. The results from simulation show that the low impact development practices are efficient in mimicking the pre-development hydrologic conditions of the landscape to a great extent.
