No-Rise Analysis for Riverfront Clay Cap
Introduction
A No-rise analysis was performed on the Mississippi River at Wood River, Illinois. The purpose of this analysis is to provide a no-rise finding for construction of a clay cap at the river side toe of the wood river levee, which will tie a subsurface cutoff wall into the existing levee section. Figure E1 below shows the project location.
Figure E1- Wood River Cutoff Wall Project Location
Purpose
A No-rise study was performed because of proposed construction of a Clay throughseepage cap at the levee toe. The study was done to verify that the clay cap would not cause a water surface elevation rise greater than 0.005 feet. The throughseepage clay cap is located at the riverside toe of the levee on the left overbank of the Mississippi River. The clay cap is approximately 3600 feet long, the width varies and is approximately 20 feet wide, and it extends approximately 6 feet above the ground surface. Figure E2 below shows the location of the clay cap.
Figure E2 – Clay Cap Location
No-Rise Engineering Methods
The no-rise analysis of the Mississippi River was accomplished through the use of hydraulic modeling software HEC-RAS, Version 5.0. The existing model had one cross section that ran through the proposed clay cap location. The existing cross sections were located at station 198.81 and 199.34. One additional cross section was interpolated at river mile 199.08 in order to represent the wall length.
The existing condition geometry was modified at both sections 198.81 and 199.08, adding protrusions, which vary between 20 and 30 feet wide, and 6 feet in total depth in order to create the with-project geometry. The station to be modified in each cross section was chosen based on intersecting the approximate elevation of the clay cap with the existing geometry cross sections on the left bank. Figure E3 and E4 show the modified cross sections, comparing existing geometry to the geometry of the clay cap. No
Datum shift was used between the Cutoff wall plans and model, because the cross sections of the model are approximations of the channel geometry, and do not exactly match the channel. The actual thickness, depth, and elevation of the clay cap will vary over the length of the cutoff wall, but an approximation had to be made in order to make a conservative, representative model utilizing the cross sections in the model.
The cross section layout is shown in Figure E5.
Figure E3- 198.81 Cross Section Geometry Comparison
Figure E4- 199.08 Cross Section Geometry Comparison
Figure E5- 199.08 Cross Section Geometry Comparison
The no-rise was analyzed using the 1% chance annual exceedance discharge for the Mississippi River.
Water surface elevations were compared between the existing geometry and proposed geometry with the clay caps. Water surface elevations can be seen in Table E2 at the end of this document.
Conclusions and Data
The no-rise analysis was performed in order to evaluate potential impacts of a clay capped cutoff wall. The model profiles resulted in no difference between the existing and proposed plans. The no-rise analysis determined that that the clay cap will not cause a significant rise in water surface elevation.
