Lecture 3 - Explanation of different aspects that influence porosity

Better Water Resources Management: (2)

Quick overview of the course

Module 1 - What is soil texture and how to determine it cost effectively?

Lecture 1 - What is soil texture triangle and how you can determine soil type from it? (2:36)
Lecture 2 - Cost efective way to determine soil type - by feel procedure (3:48)
Lecture 3 - Explanation of different aspects that influence porosity values (11:44)

Module 2 - Soil moisture as first main quantity to measure for groundwater recharge estimation

Lecture 1 - Basis for groundwater recharge estimation - Soil Water Content Measurement and Application (67:50)
Lecture 2 - Improving accuracy of dielectric soil moisture sensors measurements for groundwater recharge estimation (67:11)
Lecture 3 - Finally practical things! Field guide for installing soil moisture sensors (8:09)

Module 3 - Water Potential, next quantity to measure to estimate groundwater recharge from precipitation

Lecture 1 - Soil Water Potential 101 (45:59)
Lecture 2 - Soil Water Potential 202 - Measuring Water Potential in the field (51:58)

Module 4 - How to determine saturated and unsaturated hydraulic properties of soils above groundwater level in the field?

Lecture 1 - Determination of soil water retention curve (5:50)
Lecture 2 - How to use soil water retention curve to get unsaturated hydraulic parameters which we need to "feed" the mathemathical model? (4:40)
Lecture 3 - Do not have a lab to get soil retention curve? There is the software with scientific basis to get unsaturated hydraulic conductivity

Module 5 - Finally, groundwater recharge rate determination using numerical model Hydrus 1D

This is finale lecture, will be held live for now, just write me on my email and we will set up 30 minute long Zoom meeting. Recording will be available soon.
