“…Over-pumping of groundwater is underpinned by three major issues: (i) an exponential increase in developing world populations; (ii) a finite available water resource; and (iii) a reduction in recharge owing to the widespread and rapid sealing of urban soils (Braadbaart and Braadbaart 1997). As a consequence of poor regulation and management of groundwater resources, many developing countries end up with particularly depleted groundwater tables, which has consequences for continued water resource utility; reduced self-cleansing capabilities and the emergence of geophysical hazards (Ozdemir 2015).…”

As urban space continues to expand to accommodate a growing global population, there remains a real need to quantify and qualify the impacts of urban space on natural processes. The expansion of global urban areas has resulted in marked alterations to natural processes, environmental quality and natural resource consumption. The urban landscape influences infiltration and evapotranspiration, complicating our capacity to quantify their dynamics across a heterogeneous landscape at contrasting scales. Impervious surfaces exacerbate runoff processes, whereas runoff from pervious areas remains uncertain owing to variable infiltration dynamics. Increasingly, the link between the natural hydrological cycle and engineered water cycle has been made, realising the contributions from leaky infrastructure to recharge and runoff rates. Urban landscapes are host to a suite of contaminants that impact on water quality, where novel contaminants continue to pose new challenges to monitoring and treatment regimes. This review seeks to assess the major advances and remaining challenges that remain within the growing field of urban hydrology. ARTICLE HISTORY

“…Semarang City experiences land subsidence of about 8 -11 centimeter per year [5], caused by a combination of alluvium soil consolidation, massive groundwater extraction and a heavy construction load [6] [7]. In both cases, the intensive growth of industrial areas, settlements and population, leads to increased demand for clean water extracted with confined aquifers, and accelerates land subsidence [3] [8]. In addition, the combination of the land subsidence and sea level rise in the coastal area further increases the area's exposure to land subsidence, since the rise of the sea level renders coastal areas more unstable.…”

Land subsidence can have a considerable impact on the socio-economic viability of areas. In urban areas, land subsidence tends to damage buildings and infrastructures gradually, while in rural peat land it slowly destroys vegetation. The damages will worsen since climate change has further implications for the areas affected by land subsidence. In Indonesia, the response to land subsidence varies in different areas in terms of awareness, urgency and action on the part of both public authorities and land users. This paper systematically investigates these varied responses in urban and rural peat land areas. Interviews with experts and surveys of 330 land users in selected sub-districts were conducted and further supplemented by focus group discussions. We found that both the public authorities as well as the land users' responses were considered as of limited value to contest land subsidence. We suggest that the endorsement of land users' response into governmental policies would make a significant difference in improving land subsidence management.

“…In some areas of the world groundwater levels of major aquifers are rapidly declining as an effect of unsustainable pumping and insufficient recharge. This is for instance the case in West Java, Indonesia; Dhaka, Bangladesh; and Beijing, China (Braadbaart and Braadbaart, 1997;Hoque et al, 2007;Zhou et al, 2012). Large-scale hydrological models have become increasingly popular in assisting water resources management of large aquifer systems (Casper and Vohland, 2008;Goderniaux et al, 2009;Branger et al, 2010).…”

Abstract. Groundwater overdraft has caused fast water level decline in the North China Plain (NCP) since the 1980s. Although many hydrological models have been developed for the NCP in the past few decades, most of them deal only with the groundwater component or only at local scales. In the present study, a coupled surface water-groundwater model using the MIKE SHE code has been developed for the entire alluvial plain of the NCP. All the major processes in the land phase of the hydrological cycle are considered in the integrated modeling approach. The most important parameters of the model are first identified by a sensitivity analysis process and then calibrated for the period 2000-2005. The calibrated model is validated for the period 2006-2008 against daily observations of groundwater heads. The simulation results compare well with the observations where acceptable values of root mean square error (RMSE) (most values lie below 4 m) and correlation coefficient (R) (0.36-0.97) are obtained. The simulated evapotranspiration (ET) is then compared with the remote sensing (RS)-based ET data to further validate the model simulation. The comparison result with a R 2 value of 0.93 between the monthly averaged values of simulated actual evapotranspiration (AET) and RS AET for the entire NCP shows a good performance of the model. The water balance results indicate that more than 70 % of water leaving the flow system is attributed to the ET component, of which about 0.25 % is taken from the saturated zone (SZ); about 29 % comes from pumping, including irrigation pumping and non-irrigation pumping (net pumping). Sustainable water management analysis of the NCP is conducted using the simulation results obtained from the integrated model. An effective approach to improve water use efficiency in the NCP is by reducing the actual ET, e.g. by introducing watersaving technologies and changes in cropping.
