Title: Analysis of bofedales and their health by applying machine learning to satellite images

Abstract: The project has 3 main objectives:

  1. Research and development of a tool which identifies bofedales structure from other vegetation, dessert, etc. - referenced as “bofedales identifier”.
  2. Research and development of a tool which classifies bofedales either as healthy or unhealthy - referenced as : “bofedales health classifier”
  3. Research and development of a tool which assesses the dynamics and the evolution of bofedales. The first two tools are based on Deep Learning (subset of Machine Learning). In particular using a specific type of Neural Network: Convolutional Neural Network (CNN) in order to classify the examined bofedales. The train set of the neural networks is composed of satellite images and the respective success rate of the classification procedure is validated on completely unseen images. The tool in the third part of the project features how to make use of the available time-series data of satellite images and calculates various indices such as NDVI, NDWI as a function of time. Techniques such as time-series forecasting are then further applied to the calculated values in order to examine how bofedales change and to forecast future dynamics. The technologies used in the development of the above mentioned tools are Python, Colab, TensorFlow, Google Earth Engine and Google Earth.

Title: Fotogrametría con RPAS

Abstract: En los últimos años los vehículos aéreos no tripulados (UAVs) conocidos como Remotely Piloted Aircraft Systems (RPAS) comúnmente Drones, se han vuelto una herramienta indispensable para la recolección aérea de datos a partir de varias imágenes verticales y oblicuas, utilizando procedimientos eficientes en menores tiempos y con mayor precisión. Para ello se describirán los tipos de RPAS, los términos fotogramétricos, el flujo de trabajo conformado por tres fases: la preparación fotogramétrica; que abarca la planificación del vuelo automático, ubicación de puntos de control, estimación meteorológica, los índices Kps y la restricción zonal; en la segunda fase, el Vuelo fotogramétrico, que realiza la verificación meteorológica in situ, el índice Kp, monitoreo del RPAS con el backup de las fotos y la tercera fase, el Pos proceso fotogramétrico, que comprende el proceso inicial, el proceso de georreferenciación y proceso final a través del software fotogramétrico.

Title: Assessing Environmental Quality in the Rio Cañete Drainage Basin The Andean River Shrimp (Cryphiops caementarius) as a Bioindicator Species

Abstract: The Andean River Shrimp (Cryphiops caementarius) is an important economic and cultural resource. We propose that it can be used to assess water and environmental quality and better understand trace metal transfer, bioaccumulation and environmental impact in Andean rivers. This work is readily divided into four areas of study. Firstly, a comparative study of environmental quality using DNA barcoding along with biotic and diversity indices. Secondly, using the Andean River Shrimp, to measure the bioaccumulation of trace metals (using ICP-MS). Thirdly, to describe pathways of trophic transfer in the Rio Cañete using Andean River Shrimp diet alongside invertebrate and vegetative tissue analyses and, fourthly, to identify the impact of trace metal accumulation on this species and its environment.

Title: River Water Geochemistry: Cañete River

Abstract: This talk will look at the Cañete River Basin. After introducing the watershed we will look at the factors that affect river water chemistry including rainwater, groundwater, geology, mining and other anthropogenic factors. The geology of Peru is dominated by the eastward subduction of the Nazca plate under South America. This has given rise to the Andean Mountains which in turn supply the water for most of Western Peru. The geology in Cañete is dominated by predominately carbonate sedimentary rocks in the upper basin, giving way to younger igneous rocks associated with the active volcanic arc in the middle basin and the older intrusive Coastal Batholith at the coast. This gives the Cañete Basin its unique characteristics and beautiful scenery, it also controls the chemistry of the tributaries which in turn control the chemistry of the main river. Initial results from this project suggest that in general the water in the river is of a very high standard with very little contamination. The chemistry of the river, and its sediments is dominantly controlled by the geology, with varying contribution from hydrothermal waters and minor anthropogenic factors predominantly affecting the tributaries. The significant proportion of Jurassic and Cretaceous carbonate rocks is reflected in the high to moderate pH, high alkalinity and major ions dominated by bicarbonate and calcium. The high alkalinity in the river acts as a buffer to any acidic inputs, be they geological or from anthropogenic factors such as mining or agriculture, and means that the river is able to safely support many aquatic species such as trout and shrimp.

Title: Remote sensing and environmental change of the Cañete valley

Abstract: We use satellite images to analyze the vegetation around the Cañete Valley. Vegetation indices provide a quantitative measure for vegetation cover as well as large-scale changes in the past 20 years. We find two major types of changes. One is caused by seasonality and the other is a response to trend changes over the past two decades. We identify key points of interest along the Rio Cañete and its associated tributaries. We also promote the need for gathering ground truth information to confirm hypotheses that arise from remote sensing observations.

Online platform is realeased!

Hi! Welcome to the first live version of the CavEP online distribution platform!

You will notice that the look of the website has changed from the beta version. I have completely revamped both the style and functionality. Hopefully this should make it easier to navigate and find relevant information.
