The invention disclosed herein includes apparatus and a method for enhancing the evaporation rate of leachate from leachate evaporator ponds. The HIAP apparatus and method promotes enhances evaporation by providing heat from high powered industrial heat lamps that direct heated air and heat energy across the air/leachate liquid interface of the evaporator pond surface to increase the evaporation rate of leachate from the evaporator pond.

A construction management system includes: a current topography data acquisition unit configured to acquire current topography data indicating a current topography of a construction site; a design topography data acquisition unit configured to acquire design topography data indicating a design topography of the construction site; a construction plan data calculation unit configured to calculate construction plan data including earth cutting plan data and earth banking plan data by collating the current topography data with the design topography data; and a construction plan data output unit configured to output the construction plan data to an output device. The construction plan data output unit causes an output device to output at least two of the design topography data, the cutting plan data, and the banking plan data in parallel.

A Slope Stability Lidar that directs a beam of optical radiation into an area on a point by point basis, each point having an elevation and azimuth and a processor that acquires data and processes the data to compile direction data, range data and amplitude data for each point, segments the acquired data into blocks of data defining a voxel, averaging the acquired range data within the voxel to produce a precise voxel range value for each voxel, comparing voxel range values over time to identify movement and generating an alert if movement exceeds a threshold.

An assembly for protecting an area from sand drift accumulation comprises a sand berm having an exposed surface that is chemically stabilized using a stabilizing agent and a fence embedded in the exposed surface of the sand berm at an angle to vertical. The fence deflects wind flow directed toward the sand berm downwards, protecting the area downwind from sand drift accumulation.
