© 2015 ASCE.The Cache Creek Settling Basin (CCSB) is subject to inflows with high sediment concentration. Originally designed to protect the floodway capacity in the Yolo Bypass, current performance of the CCSB is in question following over 70 years of high sediment loads. Operation plans dictate that alterations be made to the levees and/or overflow weir in the basin when trap efficiencies are less than 30 percent. CCHE2D model, a 2D depth-averaged hydrodynamics and sediment transport model, is applied to simulate the sediment transport process in the CCSB. Simulations are performed to evaluate the trap efficiency in the basin under current bathymetric conditions. Possible alternatives, such as raising the overflow weir, and removing portions of the levee, are also evaluated. Recent and historical flows and sediment loads are simulated. Preliminary modeling results are presented here.

Two-dimensional unsteady flow modeling of flood inundation in a leveed basin Carr, K.J.; Tu, T.; Ercan, Ali; Kavvas, M.L.; Nosacka, J. (2015-01-01) © 2015 ASCE.The Cache Creek Settling Basin (CCSB) is a 14.5 square-kilometer sediment retention basin designed to trap sediment and reduce sediment loads into the Yolo Bypass. The basin, and the 13-kilometer stretch of leveed creek from the United States Geological Survey (USGS) Cache Creek at Yolo gauge (11452500) to the upstream boundary of the basin, were engineered to safely conduct flows up to 850 cubic meters per second with approximately 1-meter of freeboard. The sole purpose of the basin is to retai...
Two-Dimensional Sediment Transport Modeling under Extreme Flood at Lower Cache Creek, California Tu, Tongbi; Carr, Kara J.; Ercan, Ali; Trinh, Toan; Kavvas, M. Levent; Brown, Kevin; Nosacka, John (2017-01-01) © ASCE.Sediment transported along with extreme flooding may greatly affect flood conveyance and associated operations and management in the lower cache creek system. In this study, the relative sediment capture and transport in lower cache creek, under current bathymetric conditions and one modification alternative (2A), is evaluated. Sediment dynamics in the lower cache creek system, which includes a floodplain and settling basin, are evaluated under extreme flow events. Of particular interest is the sedim...
A Case Study for Determination of Hydrological Parameters in HEC HMS In Computing Direct Runoff Akay, Hüseyin; Baduna Koçyiğit, Müsteyde; Yanmaz, Ali Melih (null; 2016-09-23) This study deals with the computation of the direct runoff of a precipitation pattern recorded in a watershed in Western Black Sea Region, Turkey. The aim is to perform a hydrological parameter evaluation using HEC-HMS for a basin with an outlet at Bayıryüzü stream gaging station situated close to Ulus town. The basin is highly mountainous along the rivers and forestry. The basin takes large amounts of rain all year round and the runoff of the basin flows into Ulus stream where more frequent flooding with d...
Effects of drying on Atterberg limits of pyroclastic soils of Northern Turkey Huvaj Sarıhan, Nejan (2018-09-15) In this study, the effects of drying on Atterberg limits is investigated using 30 soil samples taken from 0.2 m to 4 m depths, from nine different landslide sites in pyroclastic deposits in Northern Turkey. Samples for Atterberg limits are prepared by (i) starting from in-situ moisture content without any drying, (ii) drying at 60 degrees C and (iii) drying at 110 degrees C. The range of liquid limit values is 35%-103% and plasticity index is 0%-37% when samples are prepared from their in-situ moisture cont...
Investigation of safe and sustainable yields for the Sandy Complex aquifer system in the Ergene River basin, Thrace Region, Turkey OKTEN, S; Yazıcıgil, Hasan (2005-05-01) This study aims to determine the safe and sustainable yields for the Sandy Complex aquifer system in Ergene River basin in northwestern Turkey. A numerical ground-water flow model was developed for the Sandy Complex aquifer, which is the most productive and the most widespread aquifer in the basin. The finite difference ground-water model was used to simulate steady and unsteady flow in the aquifer. The model was calibrated in two steps: a steady-state calibration, by using the observed ground-water levels ...
