In both GIS and terrain analysis, drainage systems are important components. Owing to local topography and subsurface geology, a drainage system achieves a particular drainage pattern based on the form and texture of its network of stream channels and tributaries. Although research has been done on the description of drainage patterns in geography and hydrology, automatic drainage pattern recog...

The paper describes the results of a study, based on literature review and interviewing of practicing engineers, examining pavement subsurface drainage systems in the UK. Details are provided of the most common drainage systems, the problems frequently encountered and methods by which these problems can be remediated and prevented. Case studies have been included to provide examples of the dete...

Climate change and urbanization are converging to challenge city drainage infrastructure due to their adverse impacts on precipitation extremes and the environment of urban areas. Sustainable drainage systems have gained growing public interest in recent years, as a result of its positive effects on water quality and quantity issues and additional recreational amenities perceived in the urban l...

The rapid drainage of supraglacial lakes injects substantial volumes of water to the bed of the Greenland ice sheet over short timescales. The effect of these water pulses on the development of basal hydrological systems is largely unknown. To address this, we develop a lake drainage model incorporating both (1) a subglacial radial flux element driven by elastic hydraulic jacking and (2) downst...

In this paper, the river network is divided into sub-networks forming a hierarchy of drainage systems following the Horton order. Then, drainage systems are rearranged based on their pattern to obtain more homogeneous drainage systems which do not necessarily follow the Horton order. Such reorganization facilitates the description of the network system. Such organization can be useful for terra...

The analysis of drainage morphometry is usually a prerequisite to the assessment of hydrological characteristics of surface water basin. In this study, the western region of the Arabian Peninsula was selected for detailed morphometric analysis. In this region, there are a large number of drainage systems that are originated from the mountain chains of the Arabian Shield to the east and outlet i...
