AGRI DRAINAGE CAN PROVIDE EFFECTIVE WATER MANAGEMENT
Due to the accuracy of the LiDar survey done on the land, as discussed in our previous newsletter, we can now determine whether the problem is surface or subsurface and perform a detailed analysis of the farm as a whole as well as provide in-depth details on specific fields. Combined with our on-site tests we are now able to apply the correct and most effective solution as well as determine the exact cause of the problem areas and where to most effectively channel the water without causing further problems.
A field plan to determine where subsurface drainage is needed.
On the new centre pivot to be installed on this farm, it was determined that there are both surface and subsurface drainage problems. Therefore, phase 1 will be land forming and phase 2 subsurface drainage installation.
Analysis to plan overall water management.
Extreme rainfall simulation on existing topography shows areas where surface drainage is required.
EROSION RISKS CAN BE PREVENTED
With the latest software, erosion risks can be analysed and prevented by stimulating extreme rainfall events on both the existing topography and the proposed topography.
PONDING PROBLEMS CAN BE DETERMINED
Ponding problems of the existing topography can be determined and again verified to be solved on the proposed topography.
Ponding analysis on the existing surface of a field, showing actual losses.
Ponding analysis of the proposed topography of a field after land forming.
1. SURFACE DRAINAGE PLAN
By compiling a proper surface drainage plan, the number of contours while still preventing erosion, this is achieved by placing them in the most effective places.and waterways can be minimised
2. SUBSURFACE DRAINAGE PLAN
A detailed subsurface drainage plan can be designed where the problem is determined to be.
A low spot on the farm that seemed impossible to drain turned out to be easy with a simple waterway in the right place.
