This package contains images and videos of active hydraulic shortcuts in agricultural areas of the municipalities of Zürich and Rümlang, Switzerland. More information on hydraulic shortcuts and their relevance for pesticide transport in agricultural areas are provided in the following doctoral thesis: https://doi.org/10.3929/ethz-b-000539927 The pictures and videos in this package are intended to be used for outreach or training of farmers, etc. and can be used freely (creative commons license). The pictures and videos were taken on 13 July 2021 between 17:23h and 17:55h (UTC+2h), a few hours after a large two-day rain event. The precipitation measured at a nearby rain gage (station Affoltern, MeteoSchweiz; 47.427694, 8.517953) equalled 41.5mm on the 12th of July, and 34.7mm on the 13th of July. The images and videos were taken at six different locations. The situations that are visible on these images and videos are described in the following. For each location, latitude and longitude is indicated in brackets (WGS84 coordinate system). - **Location 1** (47.42726, 8.52567): Surface runoff on a farm track. Since the farm track is elevated in the middle, water flows at the left and right edge of the farm track. Only at one specific location surface runoff changes from the left to the right side. - **Location 2** (47.43118, 8.52572): Surface runoff flows along one edge of a farm track. - **Location 3** (47.43580, 8.52877): Surface runoff accumulates on a potato field, flows on a asphalt road, and then into an inlet of the road storm drainage system. - **Location 4** (47.44077, 8.52534): Surface runoff flows from a corn field on an asphalt road, and then into an inlet of the road storm drainage system. - **Location 5** (47.43819, 8.50848): Surface runoff accumulates on a field with bare soil, causing erosion. At the field border with the lowest elevation, surface runoff flows onto a small asphalt road and then for around 180m along this road. Finally, the surface runoff flows into an inlet of the road storm drainage system of a larger asphalt road. - **Location 6** (47.43837, 8.50621): Surface runoff formed on grassland flows into an inlet of the storm road drainage system. This occurs either directly, or via the road.

Polycrystalline diamond compact (PDC) bits are routinely used in the oil and gas industry for drilling medium to hard rock but have not been adopted for geothermal drilling, largely due to past reliability issues and higher purchase costs. The Sandia Geothermal Research Department has recently completed a field demonstration of the applicability of advanced synthetic diamond drill bits for production geothermal drilling. Two commercially-available PDC bits were tested in a geothermal drilling program in the Chocolate Mountains in Southern California. These bits drilled the granitic formations with significantly better Rate of Penetration (ROP) and bit life than the roller cone bit they are compared with. Drilling records and bit performance data along with associated drilling cost savings are presented herein. The drilling trials have demonstrated PDC bit drilling technology has matured for applicability and improvements to geothermal drilling. This will be especially beneficial for development of Enhanced Geothermal Systems whereby resources can be accessed anywhere within the continental US by drilling to deep, hot resources in hard, basement rock formations.
