Abstract. Land use change are become issues for many river basin in the world, including Cikapundung River Basin in West Java. Cikapundung River is one of the main water sources of Bandung City water supply system. In the other hand, as one of the tributaries of Citarum River, Cikapundung also contributes to flooding in the Southern part of Bandung. Therefore, it is important to analyze the effect of land use change on Cikapundung river discharge, to maintain the reliability of water supply system and to minimize flooding in Bandung Basin. Land use map of Cikapundung River in 2009 shows that residential area (49.7%) and mixed farming (42.6%), are the most dominant land use type, while dry agriculture (19.4%) and forest (21.8%) cover the rest. The effect of land use change in Cikapundung River Basin is simulated by using Hydrological Simulation Program FORTRAN (HSPF) through 3 land use change scenarios: extreme, optimum, and existing. By using the calibrated parameters, simulation of the extreme land use change scenario with the decrease of forest area by 77.7% and increase of developed area by 57.0% from the existing condition resulted in increase of Qmax/Qmin ratio from 5.24 to 6.10. Meanwhile, simulation of the optimum land use change scenario with the expansion of forest area by 75.26% from the existing condition resulted in decrease of Qmax/Qmin ratio from 5.24 to 4.14. Although Qmax/Qmin ratio of Cikapundung is still relatively small, but the simulation shows the important of water resources analysis in providing river health indicator, as input for land use planning.

“…Moreover, climatic changes may influence runoff and erosion in the drainage basin, which in turn affects sediment discharge to the downstream delta (Chalov et al, ; Fischer, Pietroń, Bring, Thorslund, & Jarsjö, ; Leeder, Harris, & Kirkby, ; Törnqvist et al, ). Climate related shifts in the flow regime of rivers (e.g., magnitude of floods) can also influence the supply of sediment and its distribution within deltas (Zhao et al, ; Stern et al, ; Chalov, Thorslund, et al, ).…”

The Selenga River delta (Russia) is a large (>600 km 2 ) fluvially dominated fresh water system that transfers water and sediment from an undammed drainage basin into Lake Baikal, a United Nations Educational, Scientific, and Cultural Organization World Heritage Site. Through sedimentation processes, the delta and its wetlands provide important environmental services, such as storage of sediment-bound pollutants (e.g., metals), thereby reducing their input to Lake Baikal. However, in the Selenga River delta and many other deltas of the world, there is a lack of knowledge regarding impacts of potential shifts in the flow regime (e.g., due to climate change and other anthropogenic impacts) on sedimentation processes, including sediment exchanges between deltaic channels and adjacent wetlands. This study uses field measurements of water velocities and sediment characteristics in the Selenga River delta, investigating conditions of moderate discharge, which have become more frequent over the past decades (at the expense of peak flows, Q > 1,350 m 3 s −1 ). The aims are to determine if the river system under moderate flow conditions is capable of supporting sediment export from the main distributary channels of the delta to the adjacent wetlands. The results show that most of the deposited sediment outside of the deltaic channels is characterized by a large proportion of silt and clay material (i.e., <63 μm). For example, floodplain lakes function as sinks of very fine sediment (e.g., 97% of sediment by weight < 63 μm).Additionally, bed material sediment is found to be transported outside of the channel margins during conditions of moderate and high water discharge conditions (Q ≥ 1,000 m 3 s −1 ). Submerged banks and marshlands located in the backwater zone of the delta accumulate sediment during such discharges, supporting wetland development. Thus, these regions likely sequester various metals bound to Selenga River sediment.

“…Daily streamflow boundary conditions below each dam ( Figure 1) for the historical HSPF model run were compiled and input directly to the model (Stern et al, 2016). To develop future time series of outflow for each reservoir site, a combination of models was applied to simulate future managed flows that reflected the influences of reservoir operational rules, diversions, and groundwater pumping (Knowles & Cronkite-Ratcliff, 2018).…”

Sedimentation and turbidity have effects on habitat suitability in the San Francisco Bay-Delta (Bay-Delta), concerning key species in the bay as well as the ability of the delta marshes to keep pace with sea level rise. A daily rainfall runoff and transport model of the Sacramento River Basin of northern California was developed to simulate streamflow and suspended sediment transport to the Bay-Delta for the next century (water years, WY2010-2099). The model was calibrated to historical streamflow and sediment data and applied using 10 Global Climate Models with two representative concentration pathways (RCP) each for WY1980-2099 from the IPCC 5th Assessment Report. Results indicate average increases in peak streamflow of +58% and +66% for the RCP 4.5 and 8.5 ensembles, respectively, by mid-century and +62 and +96% by end-of-century. Sediment loads increased by +39% and +69% by end-of-century. Suspended sediment concentrations (SSC) increased on average by +4.6% and +6.7% for RCP 4.5 and 8.5, respectively, by end-of-century. Individual scenario results varied, and statistically significant increasing trends of sediment loads to the Bay-Delta were found for the RCP 4.5 and 8.5 ensembles and five individual scenarios. Increased suspended sediment loads may have negative effects such as contaminant transport but also have positive effects that help protect against sea level rise, increase turbidity and fish habitat, and sustain wetland habitats in the Bay-Delta. Plain Language Summary The health of the San Francisco Bay-Delta depends on a sediment supply that has been recently declining. Future climate scenarios were run through a model to determine changes in streamflow and sediment transport. Results from the model showed increases in large flow events and sediment transport over the next century. Increased sediment supply can help buffer wetland habitats against the deleterious effects of sea level rise with benefits to native fishes.
